J-Lo and A-Rod — sometimes called by the mashup name J-Rod — have been dating for about two years.

“I’m glad I didn’t have to wait 16 years for this yes,” A-Rod tweeted at 10:40 p.m. Saturday — a reference to the fact he played in the major leagues for 16 years before he earned his first World Series ring, in 2009 with the Yankees.

“From baseball games, to travelling across the world to shows in Vegas. We have done it all together and every moment with you is cherished,” Rodriguez, 43, gushed to Lopez in an Instagram tribute posted Feb. 4.

Lopez wrote the day before on Instagram that the former Yankee slugger makes “my world a more beautiful safe and stable place…in the midst of our ever-changing, ever-moving life.”

The couple has put up plenty of gushing social media posts — but whether they’d eventually wed has been a mystery.

Lopez shut down engagement rumors on the Ellen show in November when she told DeGeneres she wasn’t sure if her and Rodriguez would tie the knot.

Lopez, a dancer, singer and actress, is currently a judge on NBC’s World of Dance—a competition show featuring dancers from all over the world.

Rodriguez, who played 22 seasons in Major League Baseball — including 12 seasons with the Yankees — retired in 2016. He is an on-air analyst on ESPN’s “Sunday Night Baseball” and as an adviser for the Yankees.
